DUST-COLLECTOR.

SPECIFICATION forming part of Letters Patent N o. 527,940, datedOctober 23, 1894.

Application filed August 18, 1894i Serial No. 520,650. (No model.)

To .all whom t may concern:

Be it known that I, ALLEN C. BRANTING- HAM, a citizen of the United States, residing at Toledo,in the county of Lucas and State of Ohio, have invented certain new and useful `Improvements in Dust-Collectors, of which the following is a specification.

My present invention consists in certain improvements upon that shown and described 1o in my application, Serial No. 505,294, iled March 22, 1894,whereby the hammer structures are moved bodily into and out of position to be operated, instead of being pivoted as shown in said application; the `hammerx 5 handles also preferably being hinged instead of formed of spring material, and the ham mers thus enabled to operate by their own `gravity instead of under spring force.

Said improvements will be first fully dezo scribed, and then specifically pointed out in the claims. l Y

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure 1 is atop orplan view of adust collector embodying one form of my present improvements; Fig. 2,a side elevation of the same, the central portion being broken away; Fig. 3, afragmentary top or plan view similar to a portion of"Fig. 1, on a larger scale; Fig. 4, a detail sectional view on the dotted line 4 4 Fig. 3; Fig. 5, a detail sectional view `on the dotted line 5 5 Fig. 3; Fig. 6, a detail sectional view on the dotted line 6 6 Fig. 3; Fig. 7, a view similar to Fig. 3 showing an alternative construction; Fig. 8, a detail sectional view on the dotted line 8 8 Fig. 7; Fig. 9, a detail sectional view on the dotted line 9 9 Fig. 7, and Fig. 10 a view similar to Fig. 9 illustrating another alternative construction.

In Figs. 1 to 6`inclusive the movetnentis secured by pivoted straight levers operated by the hammer structures themselves from one another as they are respectively moved by the wedge. l

In Figs.7 to 9 inclusive a spring is substituted for the levers, and in Fig. l0 a weighted bellcranklever is substituted for the straight lever, and the traveling wedge is positioned 5o to operate vertically instead of horizontally.

The springs of Figs. 7 to 9 are merely a substit ute for the levers, and are regarded for this purpose as mechanical equivalents therefor, and the lever shown in Fig. 10 is simply a lever of another form fromwthose shown in Figs. 1 to 6, with the consequent re-arrangement of the operating wedge. All the forms, therefore, I regard as clearly equivalent to each other, as all accomplish the saine purpose, viz: the movement of the hammer 6o structure bodily back and.` forth, into and out of the path ofthe hammer-operating device.

`In said drawings the portions marked A represent the frame-work; B, the dust-collec t-- ing tubes; C, the driving shaft; D, the hammer-operating shaft; E and F, shafts for chain belts carrying the dust receptacles; G, said dust receptacles; H, a support for the hammer structure; l, the hammers; J, levers for t throwing the hammers intoand out of op- 7o erative position, and K `thechain-carryingV wedges for operating the hammer structures.

The various parts A B C D E F and G, and also the various gears, pulleys and belts, are substantially the same as corresponding parts `7 5 lshown and described in my above-mentioned application, and, as their construction and operation are plain and` easily understood, need not be further described herein, except incidentally in describing the invention, and 8o such incidental description will be made suficient for the purposes of this application.

The support H for the hammer structures is a plain fiat bar or timber of considerable width which extends from end to end of the machine, and upon which all` the hammer structures and thepivots, pins and levers or springs are mounted or secured.

`Thehammers I are mounted upon the forward or swinging end of the two-part hamgo mer-handle l I2, said two parts being united by the hinges t'. The parts l2 are secured between blocks H on the `bar H which are preferably recessed or dovetailed at their lower corners to receive Wings or flanges on said parts I2, and these parts are thus rigidly secured from any but a reciprocating movement.

As above stated, the parts I are hingedjto the parts I2 by hinges c', and are thus free to be raised and let fall at appropriate times by roo as the hammer structures are successively thrown forward in position to be so operated.

The levers J are centrally pivoted on studs h on the blocks H and the ends extend out alongside pins t2 projecting up from the upper surfaces of the parts I2. The operation 1s, as one of the hammer structures is thrown forward by the traveling wedge that the pin thereon will come in contact with two of these levers, one extending out in each direction, and the other ends of said levers will come 1n contact with the corresponding pins on the adJacent hammer structures, thus forcing elther or both structures back out of engagement with the hammenoperating shaft, as may happen to be the case. Usually in the regular operation of the machine the only hammer structure which is affected in this way 1s the one which has just been in operation, and this is drawn out of operative position by this means as the succeeding one is forced into such operative position, as will be readily understood.

The chain K is mounted on suitable sprocket wheels on the shafts K and K2, and is driven by the chain beltK3, which in turn is driven by a corresponding sprocket wheel ou the shaft F, said shaft being driven by the chain belts G which carry the dust receptacles, and these 1n turn driven from the shaft E, which is driven by the chain belt C from the driving shaft C. The chains K and G thus having a simultaneous movement, and the various wheels are of such a size as to insure an equal movement,so that the dust receptacles and the hammer-operating wedges shall always be in Vertical planes. Said chain K carries the hammer-operating wedges K4 which pass alongin appropriate ways provided therefor, as shown, behind the ends of the hammer structures, and force one after another of said structures forward into position to be operated by the hammer operating shaft, and, as has just been explained, through the levers J, returning the others to a position Where they will not be operated. Both the front end of the wedge and the rear ends of the hammer structure parts l2 have inclined faces where they come together, to facilitate the operation.

The operation may be briey stated as follows: The hammer-operating shaft D is in a continual rotation. The dust receptacles Gr and the wedge blocks K4 are simultaneously periodically moved from set to set of the dustcollecting tubes. Said dust receptacles coverl the lower ends of the set of tubes being operv ated upon, and receive the dust, and that one of the wedges which is at the time passing behind the hammer structures forces the corresponding hammer structure forward, so that its front end is within the sweep of the wing d on the shaft D, and, during the operation of the parts fully described in my other applications, the .hammer is raised by said wing and permitted to fall by its own gravity upon the bar carrying the set of dust-collecting tubes, and dislodging the dust, which is precipitated into the dust receptacle. As the wedge K4 passes along, the hammer structure is withdrawn out of the path of the wing d, either by the appropriate lever J, or the corresponding spring J', or the corresponding weighted bell-crank lever, J, the movement being the same in each case, and the forward movement being in each case effected by the traveling wedge, and the swinging part of the hammer being in each case hinged or pivoted upon the hinge pivot t'.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is f l. The combination, in a tubular dust collector, of a supporting frame, the dust-collecting tubes, a series of hammers, a hammeroperating shaft having a wing, and devices for moving the hammer-structures longitudinally back and forth, and thus throwing said hammers successively into the path of said wing and withdrawing the-same therefrom.

2. The combination, in a dust collector, of a series of dust-collecting tubes, a hammeroperating shaft having a wing or projection on one side, a pivoted hammer for each setof tubes, a traveling Wedge adapted to move 9 each hammer-structure successively into the path of the wing on the shaft, and suitable devices for returning said hammer-structure to position, substantially as set forth.

3. The combination, in a dust collector, of

ICO

a series of sets of dust collector tubes suitably supported at the upper ends, a hammer positioned over each set of tubes-the hammer-handle being hinged or pivoted at a suitable point, a traveling wedge for throwing the hammers forward successively, blocks between the hammer structures, levers pivoted on studs on said blocks, and pins on the hammer structures themselves which engage with and operate said levers and whereby each hammer structure is Withdrawn as the succeeding one is thrown into position to operate, substantially as shown and described. In witness whereof I have hereunto set my hand and seal, at Toledo, Ohio, this 14th day of August, A. D. 1894.
